Problems solved by technology

Although the existing volute tongues for indoor units of air conditioners can meet the requirements of use and are easy to install, due to the L-shaped structure of the air guide surface, the convection environment for wind flow at the volute tongues is poor, and uneven air flow or There are problems such as wind surge, so it often produces a lot of noise during use

Abstract

The invention belongs to the field of refrigeration equipment, and specifically discloses a volute tongue for an indoor unit of an air conditioner and an indoor unit of the air conditioner, which can effectively reduce the wind-out noise. The volute tongue for the indoor unit of an air conditioner comprises a volute tongue body, and the volute tongue body is provided with a wind guide surface; the wind guide surface is a U-shaped structure, which includes a first curved surface section, The second surface segment and the third surface segment. The air conditioner indoor unit includes the aforementioned volute tongue for the air conditioner indoor unit. By setting the wind guiding surface of the volute tongue body into a U-shaped structure that is connected by a smooth transition of the first curved surface segment, the second curved surface segment and the third curved surface segment in sequence, the wind guiding ability of the volute tongue can be improved, and the volute tongue can be improved. The convection environment with flowing wind avoids problems such as uneven air outlet and wind surge, effectively reduces the noise generated by the indoor unit of the air conditioner when it is running, and improves the air outlet capacity of the indoor unit of the air conditioner.

Description

technical field [0001] The invention belongs to the field of refrigeration equipment, and in particular relates to a volute tongue for an indoor unit of an air conditioner and an indoor unit of the air conditioner. Background technique [0002] With the continuous improvement of people's living standards, people's requirements for materials are getting higher and higher; for daily necessities such as air conditioners, people also have higher requirements for its appearance and quality. Noise, as an important indicator of customer experience during air conditioner operation, has also attracted more and more attention. It is found through research that the volute tongue has a great influence on the noise generated by the indoor unit of the air conditioner when it is running. The existing volute for the indoor unit of an air conditioner includes a volute body for being arranged in the indoor unit body and corresponding to the volute. The surface is an L-shaped structure. Alt...
